I recently purchased Song Sergeant & MPFreaker to clean up my iTunes. After running it a number of times (also MPFreaker) My iTunes is much better but still not finished. I have two initial challenges:

1) There is numerous albums still without artwork
2) And this is the one that bugs me - I have albums like a-ha - Lifelines that appears twice - one with one song and the other with the balance of songs.

I cannot see why this should be. It also happens with compilation albums they appear in the albums list for each song and not as a album (I have ticked compilations).
